Brian recently started working as a paramedic, and yesterday was his first day off. Because it was a bright and sunny day, he decided to go for a quick run along the river on the East Village pathway. As he was nearing Chinatown, he noticed an elderly lady having difficulty breathing. People started to gather around her to see if she needed any help. Brian's heart started to beat faster, and he started to sprint toward the lady. When he arrived, he checked her vital signs and asked someone to call 911. His pupils were dilated to obtain as much visual information as he could gather from the lady in distress. Which part of the nervous system is responsible for the physiological changes that Brian was experiencing? Select one: a. Stimulation of the parasympathetic nervous system and inhibition of the sympathetic nervous system b. Stimulation of both the parasympathetic and sympathetic nervous systems c. Stimulation of the sympathetic nervous system and inhibition of the parasympathetic nervous system d. Inhibition of both the parasympathetic and the sympathetic nervous systems
